Selection of the Best LNG Natural Gas Supplier with Multi-Criteria Decision-Making Techniques: Turkey Example in Current Conditions

Öz

Decision of supplier selection has a crucial importance for a firm to succeed. Liquefied Natural Gas‎ (LNG) is a crucial alternative to ensure the safety of natural gas supply in today's conditions, especially for the state of natural gas supply security. LNG supplier selection constitutes the most important key point of this process. This study aims to make the selection of the best LNG natural gas supplier for Turkey using the Analytic Hierarchy Process (AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) methods according to the current conditions. For this purpose, expert opinions, activity reports and literature reviews were made to determine main and sub criteria. AHP method is applied by using Expert Choice Software and TOPSIS was analyzed with Microsoft Excel for the best supplier choice. In addition, it has been shown that which criteria brings which alternatives forward, which criteria are decisive in the result and which are not decisive.
